Change context of Password Manager Pro

Hi!

After installing PMP it runs on our server at
https://server:7272/

But we would like to run it on

https://server:7272/passwords

What we did:
We changed the line

<Context path="" docBase="PassTrix" debug="0"/>

at the very end of the conf/server.xml to

<Context path="/passwords" docBase="PassTrix" debug="0"/>

The effect was that now we can reach the server via
https://server:7272/passwords
but it is not possible to log in! We get redirected to
https://server:7272/j_security_check
which gives us a HTTP 404 error code.

Is there something else to configure so that the pathes/links etc. are adjusted when changing the context path?

Hopefuly you can help as we really like Password Manager Pro and are happy to use it!

Thanks!
